Overview
The Harwin G125-MS11205L0R is a Gecko-Latch power-to-board connector featuring a 1.25 mm pitch and 12 positions in a dual-row configuration. Rated for 2 A current and up to 450 V, it utilizes phosphor bronze contacts with gold plating. The housing is constructed from polyamide (PA) with UL94 V-0 flammability rating. Designed for surface mount technology, it offers a straight installation angle and operates within a temperature range of -65 °C to +150 °C. Insulation resistance is specified at 10 GOhms.
Feature Summary
- Features a pin-lock latching mechanism combined with board lock retention for secure mating.
- Includes four-wall shielding to provide enhanced environmental protection.
- Utilizes gold-plated phosphor bronze contacts for reliable electrical conductivity.
- Constructed with high-temperature resistant polyamide insulation.
Applications
- Power distribution in automotive electronics
- Industrial control systems requiring robust connections
- General purpose board-to-board interconnects
Procurement Notes
Verify the specific suffix 'L0R' against official Harwin documentation to confirm reel packaging and tape specifications. Ensure compatibility with automated pick-and-place equipment by checking component dimensions and orientation markings. Cross-reference the RoHS status and material composition reports with the latest datasheet to meet regulatory requirements for your target market.
Selection Notes
Select this component when a compact, high-reliability power connection is required on space-constrained boards. The Gecko-Latch series provides superior retention compared to standard headers. Consider the 1.25 mm pitch for balanced density and current carrying capacity. Verify that the surface mount footprint aligns with the PCB design guidelines provided in the manufacturer's catalog.
Part Context
This part belongs to the Harwin Gecko-Latch family, designed for demanding applications where vibration resistance is critical. The series distinguishes itself through a unique locking mechanism that prevents accidental disengagement. It serves as a specialized solution for power delivery in environments where standard connectors might fail due to mechanical stress or thermal cycling.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific variant. Generic 1.25 mm pitch connectors may fit mechanically but will lack the Gecko-Latch retention features. Consult Harwin engineering for alternative series if availability is an issue.
